A platform including an upper deck and a lower deck longer than the upper deck, both being constructed of a light-weight sturdy material. Angular material comprises the framework of the decks. The decks are hinged together at the forward edge of the platform, which comes in contact with the roof. Male-female sleeves are attached to the inner parts of the sides and support pieces of both decks to provide support. The sleeves adjust so the platform can accommodate varying roof pitches. The bottom surface of the lower deck is covered in non-skid material to provide adhesion to the roof. The forward edge of the lower deck has extensions with holes so the platform can be secured to the roof with screws or nails.
